I, WiLLIAM JACOB KUHNS, Of Brooklyn, coiinty of Kings and State of New York, have invented acertaiu Improvement in the Process of Nickel Plating by the battery, of which the following is a specification The object of my invention is to secure a more perteetcontaetandadhesion of the nickel upon the surface of thearticle to be nickel plated an d my process is especially useful for nickel plating on iron and steel.

My improvement consists in causing a film of tin to lie between the surface of the article t-ohe nickel plated andthe filmof nickel. The oiiice of the tin is to serve as a bond of union between the substance of the article to be plated and the nickel. The surface-metal of the article has little afiinity for the nickel,

while both of these strongly adhere to tin.

The coating of .tin is given to the article to be plated in any of the known efficient methods-as, for example, by dipping in molten W. J. KUHNS.
